Description

  The present invention is a spigot in which a cap is screwed into a spout projecting at a pouring position of a liquid paper container, and when the contents are poured out from the spout (spouting tool) by tilting the container, There is no pulsation, and when the contents are completely dispensed and the container is placed in place, the contents remaining on the top of the spout will not drip out of the spout Is.

  Conventionally, as shown in FIG. 3, for example, as shown in FIG. 3, a liquid paper container (20) having a gable roof shape at the top (22) and a rectangular tube shape (21) is used over a wide range of applications. It was. In consideration of ease of use, the liquid paper container can be provided with a spout (100) projecting from the top inclined plate pouring position, and a cap (200) can be screwed and unscrewed to the spout. A mouth plug (10) to be attached to was used.

  However, when the inner diameter of the spout is 15 mm or less, the above-mentioned conventional liquid paper container cap is poured out because the spout has a small inner diameter when the contents are poured out of the spout by inclining the container. However, the replacement of the contents to be carried out with the air flowing into the container is not performed well, and pulsation may occur in the outflow state of the contents from the spout. In addition, when the dispensing of the contents was completed and the container was placed in place, the contents remaining on the top surface of the spout sometimes dripped out of the spout.

  The present invention solves the problems of the above-mentioned conventional liquid paper container caps, and even if the inner diameter of the spout is small, there is no pulsation in the state in which the contents are poured out. When the container is placed and the container is put in place, the pulsation and dripping-preventing plug with which the contents remaining on the top surface of the spout do not drip out of the spout are provided.

  That is, the first invention of the present invention is a spigot comprising a spout projecting at the pouring position of the liquid paper container and a cap screwed to the spout, and inside the spout tube of the spout, A pulsation and dripping-preventing spigot characterized in that a horizontal cross-sectional shape is provided with a cross-shaped partition, divided into four flow holes, and fine vertical grooves are provided on the entire inner surface of the four flow holes. is there.

  And as for 2nd invention of this invention, the internal diameter of the said spout is (phi) 15 mm or less, the thickness of the said partition is 0.4-1.2 mm, and the said vertical groove is 0.7 mm or less in width, The mouth plug with pulsation and dripping prevention according to the first invention, characterized in that the depth is 0.2 to 1.0 mm.

  The plug with pulsation and dripping prevention according to the present invention is provided with a partition having a cross-sectional shape in the horizontal cross section inside the spout tube of the spout, and is divided into four flow holes, and the contents are formed by tilting the container. When the water is poured out from the spout, the contents are poured out from one of the lower flow holes, and air flows in from one of the upper flow holes. This is done well in the container and as a result there is no pulsation in the outflow of the contents from the spout.

In addition, the pulsation and dripping-preventing mouth plug of the present invention has fine vertical grooves formed on the entire inner surface of the four flow holes provided by dividing the inside of the pouring cylinder with a cross-shaped partition, and the pouring of contents When the container is placed and the container is placed upright, the contents remaining on the top surface of the spout return to the inside of the spout due to the effect of capillarity of the vertical grooves provided in the entire inner surface of the flow hole. There will be no dripping outside.

  Next, an embodiment of the mouth plug with pulsation and dripping prevention of the present invention will be described in detail with reference to the drawings.

  Fig.1 (a) is a top view of the spout of a spout with a pulsation and dripping prevention of one Embodiment, FIG.1 (b) is sectional drawing.

  2 (a) is an explanatory view showing the shape of the longitudinal groove provided in the spout tube of the spout of the pulsation and dripping prevention mouth plug of FIG. 1, and FIG. 2 (b) is a longitudinal view provided in the partition. It is explanatory drawing which shows the shape of a groove | channel.

  FIG. 3 is a perspective view of an example of a liquid paper container with a stopper.

  The plug with pulsation and dripping prevention of the present embodiment is composed of a spout and a cap screwed onto the spout, and as shown in FIG. 1B, the plug attachment hole (23 of the liquid paper container (20)). ) Projecting the spout tube (110) and the annular pedestal (140) of the spout (100), and heat-sealing the upper surface of the flange (150) and the inner surface of the liquid paper container by an ultrasonic sealing method or the like. Is projected at the pouring position of the liquid paper container, and a cap is attached to the spout so that it can be screwed and unscrewed. Normally, the cap (10), in which the cap (200) is screwed to the spout (100), is protruded from the liquid paper container (20) as shown in FIG. The spout is produced by an injection molding method using a thermoplastic resin such as polyethylene, and the cap is produced by an injection molding method using a thermoplastic resin such as polypropylene.

  As shown in FIGS. 1A and 1B, the spout (100) according to the present embodiment is provided with a partition (120) having a horizontal cross-sectional shape inside the pouring tube (110). As shown in FIGS. 2 (a) and 2 (b), fine vertical grooves (131) are provided on the entire inner surface of the four circulation holes.

  The product specifications of the spout of the present embodiment are φ15 mm or less, where the inner diameter is small and pulsation is likely to occur when the contents are poured out, and the partition thickness takes into account the strength and the space of the outflow hole. In the range of 0.4 to 1.2 mm, the vertical groove has a width (w) shown in FIGS. 2A and 2B of 0.7 mm or less in consideration of the effect of capillary action. The product is designed to have a depth (d) of 0.2 to 1.0 mm.

  The mouth plug with pulsation and dripping prevention of the present invention should be used for contents whose stains are noticeable due to coloring, clumping, etc. when the contents are relatively low in viscosity and dripping outside the spout. In addition, it can be used by projecting at a pouring position of a liquid paper container such as soy sauce or liquid seasoning.
